mikuni question

[ron1026]

Looking at getting  a 42 mik for my superglide, 95bb,  Big Boyz heads, VH propipe ,37g, and was wondering if I should just  get the easy kit or the full kit which comes with a new manifold . Is there a big difference bet the stock manifold and the mikuni? I've searched the back threads but haven't seemed to find any yet.

  Thanks  Ron

 I don't think a 95 inch build would benefit from the manifold and a 42.  Maybe the SE manifold or the Mikuni manifold with the HSR 45 for about 3 more hp on the very top end.  Me, I would just get the carb and not the manifold unless you just had to do it.

I agree with L-, manifold not needed.

Easy kit      use the stock intake.

That's what I thought. Thanks all for the quick response. The amount of info that this board has available is amazing, I am extremely glad to be part of it.

Ron, not sure what your needs are, but here is some info:

Jireh PN 42-255 (Total Kit) includes 45mm Carb, breather kit, manifold, and flange- $444.95
Jireh PN 42-156 (Easy Kit) includes carb and airbox adapter- $374.95
(hope I got the PNs and prices correct!)

Looks like a $70 difference for a manifold and a a breather kit. If you already have a high flow breather with a K&N filter, then the manifold is $70. Probably not worth it. If you need the breather and air cleaner then the total kit is probably more cost effective.

I needed a breather so the cost differential was worthwhile, I bought the total kit (cost differential for the Evo is $100). I don't know if there are any real technical advantages to the Mikuni manifold. On my Evo Softail, the VOE switch interfered with the manifold. I had to do some filing to get the manifold in place- slowed me up for about an hour.

Whatever your choice is, you will do OK with the Mikuni. I have run Mikunis on several different bikes (Harleys and Beemers and dirt bikes). They fire right up out of the box every time. They are a little more difficult to tune (than an S&S). Main jet changes are easy, but jet needle changes and/or adjustments require carburetor removal, unless you have a peanut tank. When they are running rich, fuel consumption is high. Tuning instructions are thorough. Overall, I'll still take a Mik anyday.

Good luck, let us know how it works out.

the Mik42 on the stock manifold flows pretty good.  One of our members did a flow bench comparison of that carb compared to a few others, which is located in the Tech Tips section:
